Two fixes to make this test pass on MacOS9:

- the test was sloppy about filenames: "0-REGTYPE-TEXT" was used where
  the archive held "/0-REGTYPE-TEXT".
- tarfile extracts all files in binary mode, but the test expected to be able to
  read and compare text files in text mode. Use universal text mode.
